Knitting question

I finished one sleeve this weekend for the cabled pullover. While my stitch gauge was dead on, it turns out that my row gauge was not. It's a bit over. When totaled the full length, it's about an inch or inch and a half more than I'm needing.



The rings at the left of the photo will be at the hands the ones on the right will connect with the yoke near the shoulder. I don't really want to rip back because the end I left off at are on the right. If I rip too much, I risk messing up connecting to the yoke.

So what should I do?

• I can go ahead and rip it anyway and take the risk of it not fitting to the yoke correctly, but then will also possibly have the problem of having the two sleeves not looking identical.
  
• I could also leave the knitting as it is and do a hem at the very end of the sleeve once the sweater is pieced together.
  

It's possible that blocking will help some, but I doubt it.

Are there any other suggestions? How would you handle this?
